Specification of Letters Patent.

Patented Mar. '7, 1922.

Application led July 15, 1920. Serial No. 396,445.

To all whom t may conc-ern.'

Be it `known that I, STEVE JURISCH, a citizen of Hungary, residing atCleveland, inthe county Ohio, have invented certain new and usefulImprovements in Window Ventilators and Mountings Therefor, of which thefollowing is a specification. 1

This invention relates to certain new and useful improvements in windowscreens and mountings therefor. v

The primary object of the invention re sides in the provision of awindow screen and its mounting wherein the screen sectionis formed oftransparent glass plates with a wire screen positioned .between thesamewhile the glass plates or panes have registering openings therein topermit the passage of air with shields or hoods overlying the openingsupon the outwardly positioned pane to prevent the passage of rain waterinwardly through the window screen.

A further object of the invention provides for a resilient mounting forthe window screen wherein a. toothed cushioned f side strip arranged ateach side of the screen is adapted to be forced into engagement with t eadjacent part of the window frame guide, a special form of key lockingdevice being employed to prevent the removal of the screen.

With the above general objects in view and others that will appear` asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefull described, shown inthe accompanying rawings and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views,

Fi re 1 is a fragmentary rear elevationa view, partly in section of awindow frame, sash and screen constructed in accordance with the presentinvention,

Figure 3 is a horizontal sectional View taken on line III- III of Fig. lshowing the screen frame in horizontal section with the resilientmounting strips therefor enga g thei'window frame,

igure .this a front elevational View of the window screen constructed inaccordance with the present invention, partly in section to show theresilient mounting of the side strips,

Figure 5 is an enlarged fragmentary view, partly in section showing themounting strip extended by the locking bolt,

igure 6 is a .horizontal sectional View taken on line VI-VI of Fi 5showing the mounting strip extended rom the screen frame, and

Figure? is a cross sectional view taken on line "VII-VII of Fig. 4showin the spring connection between the screen rame and the mountingstrip.

Referring more in detail to the accompanying drawings, there isillustrated an ordinary construction of window frame embodying thebuilding part l having a window rame 2 arranged in the opening thereofwith the window sash 8 sliding in the guide formed by the rail 4 andparting strip 5, this construction being clearly shown in Figs. 1 .to 3.v

The screen is formed of a pair of rectangular frames 6 betweenwhich apair of lass panes 7 and 8 are clamped as shown in igs. 3, 6 and while ascreen 9 of the usual metallic construction is ositioned between 'theglass panes 7 and 8. ny desired number of registering openings 7 and 8are formedl in the panes 7 yand l8 respectively to provide for a passageof air through the window screen, while integral glass hoods or shields10. are carried by the pane 8 and overlie the openings 8 with the openends of the hoods being downwardly directed, thereby preventin thepassage of rain or other water from t e outside of the screen to theinside thereof to permit a practically free circulation of air throughthe pane openings 7 and 8 It is intended to position the screen frame inthe sash guide as illustrated in Figs. 1 to ,a bolt casing' 18 3, withthe window sash 3 lowered thereon and with the screen frame locked inthe window opening, the mounting of the screen including the provisionof a pair of T-shaped strips having the legs 11 slidably mounted betweenthe screen strips 6 with the head 12 positioned outwardly of the strips6 with the side edges Hush with the adjacent edges of the strips. Thelegs 11 of the T strips are provided with spaced circular pockets 13having a coil spring 14 received therein and anchored upon the pin 15 atthe inner end of the pocket while the opposite end of the spring 14 isanchored to a pin 16 fixed to the strip 17 within the frame sides 6,thus Aresiliently mountingthe T strip between the frame sides.

A locking device for retainin the screen resiliently mounted Within thewindow opening is more clearl shown in Figs. 5 and 6,

being countersunk within the strip 17 and having a locking lever 19pivoted upon the bolt 20 that projects through one side frame 6 and issquared upon the end .thereof as at 20" for reception of a key 2 1. Awearing late 22 is fastened to the inner edge of eac leg 11 of the Tstrips and is engaged by the locking lever 19.

With the window screen lpositioned in the window ope1 1 i s beneath t eSash 3, the key 21 rotates the s aft 20 to cause the lever 19 to engagethe mounting strip and sink the pins 22" carried by the strip head 12into the window frame, the strips moving outwardly against the tensionof the springs 11.1.I

until the lever 19 moves past its center as shown in Fig. 5, at whichtime the sprin will center the screen frame 6 and cause t e lever 19 toengage the adjacent edge of the mounting casing 18. The o posite side ofthe screen is similarly secure to the window frame so that the centralscreen frame is resiliently mounted and capable of slight movement inopposite directions.

To remove the screen from the window frame, it is only necessary toshift the locking levers 19 to a position where the levers lie withinthe mounting casingsllS, at which time the springs 14 will retract thelegs of the mounting strips between the screen frame sides as shown inFig. 4 to permit the removal of the screen from the window guides.

While there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made therein without departing from the spirit and scopeof the invention as claimed.

1. A window ventilator comprising a frame, a pair of glass panes carriedthereby with a screen interposed between the panes, said panes havingregistering -openings therein, and means overlying the openings at theouter side of the screen to prevent the passage of water therethrough. Yy

2. A window ventilator, comprising a frame, a pair of glass panescarried thereby with a screen interposed between the panes, said paneshaving registering openings there in, and hoods overlying the openingsat the outerv side of the screen to prevent the passage of watertherethrough.

3. A window ventilator comprising ,a rectangular frame, an inner and anouter glass pane carried by said frame, a screen interposed between thepanes, said panes having registering openings therein and-hoodsintegrally formed in the outer pane and overlying the openings thereinto prevent the passage of wfater therethrough.

In testimony whereof I 'ailix my signature.
